1.RTV-2 molding silicone applications

RTV -2 molding silicone use in mold making field for poly resin crafts,PU resin crafts,gypsum crafts,unsaturated resin crafts,lighting and candles crafts,plastic toy,stationery gifts crafts inducstry,large statue Buddha,relievo funiture,furniture decorative mouldings,gardern series mouldings,cemend mold,artificial stone crafts,animals and plants sculpture. toy gifts and craftwork gifts, poly technique, lightings, candles, and molds in multiple pieces.

2.RTV-2 molding silicone features 
RTV -2 molding silicone with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. It is suitable for small products or fine and precision products which is difficult to demould. This silicone rubber is one of the products with the highest use level in the production of craftwork gifts and the shrinkage is up to 2.

3.RTV -2 molding silicone instruction:
RTV -2 molding silicone Component A is white flowing liquid and component B is the curing agent. For example, take silicone rubber of 100g and add 2g curing agent for mixing evenly (silicone rubber and curing agent must be measured accurately). After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame. If you don't have vacuum machine, please add 1.2% or 1.5% curing agent so that the bubbles can bubble itself. Since the less curing agent you add, the slower the mould will curdle, the bubbles will bubble out itself.
